Note 1: DE/SYNC mode select. Normally pull high. 

When select DE mode, MODE=”1”, VS and HS must pull high. 

When select SYNC mode, MODE=”0”, DE must be grounded. 

Note 2: When input 18 bits RGB data, the two low bits of RGB data must be grounded. 

Note 3: Data shall be latched at the falling edge of DCLK. 

Note 4: Selection of scanning mode 

Note 5: Definition of scanning direction. Refer to the figure below: 


Note 6: Global reset pin. Active low to enter reset state. Suggest to connect with an RC 

reset circuit for stability. Normally pull high. 

Note 7: Dithering function enable control, normally pull high. 

When DITHB=”1”, Disable internal dithering function. 

When DITHB=”0”, Enable internal dithering function.
